I've got the Baker Super Lights and I really like them.  I used them about 45 days this season as both my inbouds/slackcountry ski and my touring/ski mountaineering ski.  For backcountry applications, you can't beat them, especially considering their weight.  I wish they were a little stiffer for the inbounds riding, but the normal Mt Baker would fit that bill. I have no experience with the Shuksan, but hte Mt. Baker has a versitile and fun geometry, which I would recomend.
